The EU and the US discussed 'parameters of possible engagement' to address the trade dispute triggered by US President Donald Trump.
Talks so far have yielded little progress and US officials don't appear to have a clear negotiating mandate from Trump yet.
The EU is working on a 'term sheet' for a potential agreement, which would set out areas for negotiations, including lowering its own duties, mutual investments, as well as easing certain regulations and standards.
European Commission President Ursula von der Leyen has made clear that her top priority is to negotiate a deal with the US that would lower or remove the tariffs.
